Dr. Jennifer Van Os’ research focuses on understanding and improving dairy animal welfare, particularly by identifying low-barrier solutions.
A footbath is one of the most important tools used on dairy farms to prevent lameness and maintain hoof health. When used properly and paired with a disinfectant, a footbath can prevent and control foot rot and digital dermatitis on dairy farms. Recently, the recommendations for footbath dimensions have changed after new research was conducted at the UW School of Veterinary Medicine.
Clinical and subclinical ketosis are the most common metabolic disorder in high-producing dairy cows, costing up to $289 per case. According to the University of Wisconsin School of Veterinary Medicine, 93% of ketosis cases occur between 5 and 30 days post-calving.
Using proper injection techniques for animal health products, including reproductive hormones, helps ensure products work effectively. In addition, it is important to safely handle animals and health products to protect both farm workers and animals.
Properly cleaning, sanitizing, and storing multi-dose syringes and transfer needles will reduce contamination from many viruses, bacteria, and fungi. The steps described here use only tap and distilled or deionzed (purified) water and do not render the equipment sterile.
Shopping for deals and managing inventory are two ways to lower livestock drug costs. Have you ever been confused by the different brands available? How do you know which is the better buy?
Green is my favorite color. Green tree buds, lawns, and pastures signal that winter is finally over. It’s very tempting to turn young stock out onto newly green pasture. We are tired of indoor feeding and cleaning, and we have fieldwork and other chores to attend to. However, tempting as it is to open the pasture gate, first remember these worm management steps.
There are times when cattle producers need to come to the aid of a downed animal. Daily observations should identify cattle that are unable to stand and there must be a plan in place for how to quickly respond to help these animals.
Bovine colostrum is the production of “first milk” from the mammary gland in the 24 hours after calving and it is the first source of nutrients for the calf. All female mammals produce it, and, in all species, it is of great importance, since it provides key antibodies, or immunoglobulins, to jump-start the immune system and determine whether the offspring survive or not.
The stomach of ruminants is made up of four compartments: the rumen, reticulum, omasum, and abomasum. Each compartment has a very specific characteristic and function to help the digestion and absorption of essential nutrients to the animal.
The importance of colostrum is no secret to dairy and livestock producers. Unlike many other species, the placenta of cattle prevents the transfer of antibodies from the dam to the calf in the uterus. Instead, calves must rely on colostrum, the cow’s first milk, to pass antibodies from dam to calf.
